Q
tactile fremitus and percussion findings for:
1 consolidation/pna
2 pleural effusion
3 pneuothorax

5 atelectasis

2
Q

best initial test for acute asthma exxacerbation?

most accurate?

A

peak expiratory flow or ABG

Q

if asx, best test to evaluate asthma is

A

Q

if asthma, PFT will show an increase of ____ in response to albuterol

Q

stepwise asthma treatment

6 steps

A

1 inhaled SABA (albuterol)
2 low dose ICS (beclomathasone, budenoside, fluticasone) OR cromolyn/theophylline/leukotriene mods

**never use LABA first or alone

6
Q

tx of acute asthma attack

A

oxygen

alpha 1 antitrypsin deficiency

8
Q

best initial test for copd is

most accurate?

brown flecked sputum and infiltrates on cxr

dx: peripheral eosinophilia, skin test reactivity to aspergillus ag, serum IgE elevated, CXR/CT infiltrates

A

urine antigen
or
culture on charcoal yeast agar

22
Q

outpatient vs inpatient tx for CAP

outpatient is macrolide (azithromycin or clarithromycin) or doxycycline
—if comorbidities do resp fluoroquinolone (levo or moxi)

inpatient is levo or moxi OR ceftriaxone + azithromycin
